CLEANING DEVICE.

Specification of Letters Patent.

Application filed August '17, 1914, Serial No. 857,024. Renewed March30, 1916. Serial No. 87,857.

To all whom it may concern:

Be it known that I, FRANK D. FARNAM, a citizen of the United States, anda resident of Edison Park, Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in CleaningDevices; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, andto the numerals of reference marked thereon,which form a part of this specification.

This invention relates to that class of cleaning devices set forth in myprior application for patent for Cleaning devices for utilizing volatileliquids, filed on the 15th day of November, 1912, Serial No. 731,591,and wherein a volatile cleaning fluid is discharged from a container bypressure generated therein by the volatilization of said liquid from theheat of the hand holding the container.

The object of this invention is to provide a device for dispensing acleaning (or other) liquid therefrom in graduated amounts and asrequired for service, and to afford a construction adapted for useeither for volatile or non-volatile liquids and so constructed as topermit the entire contents of the container to be discharged, asrequired, either through pressure generated by the expansion of theliquid or independently of such pressure, dcpendent upon the characterof the liquid used.

It is also an object of the invention to afl'ord a construction adaptedfor use in connection with a device such as set forth in my aforesaidpending application for patent wherein the liquid may be discharged bypressure from the volatilization of the liquid or by atmosphericpressure, as required, thus enabling the entire contents of thecontainer to be discharged at the rate required for use.

It is finally an object of the invention to afford a founta n brush, thedischarge from the fount of which is occasioned wholly or in part fromthe heat of the hand or may be produced mechanically, as preferred.

The invention (in a preferred form) is illustrated" in the accompanyingdrawings and herein after more fully described.

In the drawings: Figure 1 is a side elevation of a device embodying myinvention.

Fig. 2 is an enlarged, central fragmentary section thereof. Fig. 3 is asection on line 3-3 of Fig. 1. Fig. 4 is a reduced section on line 41 ofFig. 2. Fig. 5 is a reduced section on line 55 of Fig. 2. Fig. 6 is areduced fragmentary detail section taken on line 66 of Fig. 5. i

As shown in the drawings: 1, indicates a container preferably of thinmetal, having high thermal conductivity, for example, thin brass orcopper, as shown cylindric in form (though not necessarily so) andhaving a head 2, provided with peripheral flange 3, which fits withinthe'lower or discharge end of the container and is permanently andrigidly secured therein to afford a tight joint and aflording a cavityor recess at the bottom of the device to receive the brush back 1, asshown in Fig. 2. Preferably, the end of the container and the flange 3,of said bottom head, are provided on opposite sides thereof withapertures to receive pins or dowels 5, therein, which extendtherethrough and into the back of the brush at its periphery, asindicated in Figs. 2 and 4, to removably engage the brush in place. Aspring clip 6, of any suitable metal, engages around the lower end ofthe container and covers the outer ends of said pins or dowels 5, andretains the same in place, but removal of the clip permits the dowels tobe removed, thereby permitting the removal of the brush.

A flanged cover 7, tightly closes the upper end of the container and maybe applied in place either with or without a gasket, as preferred, andthe flange thereof, as shown in Fig. 1, is provided with lamp socketnotches on opposite sides thereof to receive therein each a pin 8, setin the upper end of the container and set to extend outwardly from theperiphery of the container, as shown in Fig. 1, whereby the cover or capmay be turned into rigid engagement to close the upper end of thecontainer or may be quickly removed therefrom, as preferred.

As shown, an air inlet valve 9, of any preferred construction, may beprovided at the inner side of the cap or cover 7 and the closure 10,therefor is supported by a weak spring 11, sufficient normally to holdthe closure seated and preventing escape of the contents of thecontainer against any internal pressure, but readily yielding to permitinflow of air at atmospheric pressure, venting the container therebytopermit discharge of the contents at the bottom. A discharge aperture andshort pipe 12, are provided in the bottom head of thcontainer, as shownin Fig.2, to conduct the liquid through the back of the brush and to thehair (or other) brush material. secured thereon, and as shown, a bracket1-3, is secured on the inner side of said bottom head and apertured inalincment with said-pipe 12, and extending therethrough is a valve stem14, which, at its lower end, is provided with a tapered valve closure15, affording substantially a needle valve. Abovesaid closure a collaror enlargement 16, is provided on the valve stem, and a spring 17 issecured on said stem and bears on the collar and said bracket and actsnormally to hold the valve seated. Extending diametrically across saidcontainer near the top thereof, and secured to its side walls, is a bar18, and pivotally' engaged thereon is a bent lever 19,

one arm of which extends above and parallel with said bar 18. and uponwhich engages the upperhooked end 20, of the valve stem 14. As shown inFig. 2, a portion of the wall of the container is cut away, and a thinresilient plate 22 is secured thereto in any suitable manner to coversaid cut away portion. The other end 21 of said lever 19 extendsdownwardly and laterally bearing at its free end against said plate 22.If preferred, of course, the wall or shell of the container may be madesu'iiic'iently thin to be vieldable' and resilient, in which case theentire body portion of the container may be made in one piece.

The operation is as follows: The container is filled to a suflicientextent with the liquid to be dispensed therefrom, by removing the cover7, to permit of pouring the liquid thereinto and the cover is thenreplaced, as shown in Fig. 2. A slight pressure is then brought to bearupon the weakened portion of the wall of the container,

pressing the arm 21, of the bent lever inwardly and thereby unseatingthe valve closure 15, and permitting the desired amount of the liquidcontent to be discharged to the brush through. the pipe 12. Suchdischarge in the case of volatile liquids, is materially assisted by thevolatilization of a portion of the contents because of the heat of thehand in which the container is held. Immediately upon releasing thepressure upon the weakened portion of the wall, the

valve closes and no further escape of the contents can be eflected untilthe valve is again opened, as before described.

Obviously the arrangement of Valve is such that augmentation of pressurewithin the container, acts normally to hold the valve seated so thatunder any conditions,

when the device is not in use, there can be" no escape of the volatileliquids, for example, gasolene therefrom, and in consequence, dan-' gerof. firms obviated. After a considerable quantity. of the liquid hasbeen dispensed from the container, and the level thereof" fallssuificiently low, the volatiliZ'ati'on from the heat-of the hand,although present, is

much less in extent than when a greater quantity of gasolene or othervolatile-liquid is in thecontainer, When the valve is open, therefore,atmospheric pressure assist insuring the discharge by the opening of thevalve 10, and the resulting inflow of atmos pheric air. Of course, ifdesired, an auto= matically acting discharge valve may also be providedin the bottom head 9, of the de vice, so that the device'operatesautomatically from the heat generated by the hand,

asdescribed in my said co-pending application. lVhere this constructionis used, the valve 15, need not be operated untll such time as the flowof the hydrqc'arb'On liquid v has practically ceased-*becau e ofpressure gasolener maining in the container.

exhaustion, due to the small quantity yo Obviously, by the'constructiondescribed,

the discharge of the fluid is at all times in control of the operator,and the quantity to generate material or sutfi'cient pressure to assistin the discharge,the discharge may at all'times be effected andcontrolled by means of the actuation of the lever aforesaid throughpressure exerted upon the weakened Wall 22 of the container, the liquidas discharged being replaced by atmospheric air being permitted to flowin through the valve 10'.

Of course, where non-volatile liquids" Of course, details ofconstruction may be varied through a wi'derange and I therefore do notpurpose limiting the patent granted otherwise than necessitated by theprior art.

I claim as my invention: A device of the class described, comprising acontainer, a peripherally flanged headin one end of said container, abrush fitted into the recess afforded in said head by said flange, saidhead having a passage there through for supplying fluid from said conetainer to said brush, dowels disposed in registering a ertures in saidcontainer, flange and brushto retain said arts together, a spring clipon said container oversubscribed my name in the presence of two lyingsald dowels removably to retaln them subsoribmg Witnesses. 1n position,a valve controlling the passage through said head, and lever mechanismFRANK DFARNAM' 5 Within said container operated by pressure Witnesses:
